Hi FusionAuth team,

We’re facing a critical issue with a FusionAuth Cloud tenant.

Issue

• All FusionAuth authentication requests are timing out
• Admin UI login is also inaccessible
• Requests do not fail fast they hang and then time out
• This causes a complete production outage for our application

Important behavior

• After restarting our application, only 1–2 FusionAuth requests succeed
• All subsequent FusionAuth requests time out again
• Scaling application workers does not help
• Restarting the server does not resolve the issue
• Issue persists across browsers and networks

Context

• FusionAuth Cloud (not self-hosted)
• Public status page shows everything healthy
• No recent configuration changes on our side
• Because requests never complete, we’re unable to capture request-level logs or timestamps

Question

• Can FusionAuth Cloud experience tenant-level latency or degradation where requests hang instead of returning errors?
• Is there any known mitigation or guidance for handling this scenario?

We’ve raised a support ticket as well, but wanted to check here in case this is a known pattern.

Any help would be appreciated. Thanks.
